Abstract

Carbonized Polymer Nanomaterials (CPNs) have acquired substantial research interest in recent years due to their budding applications in various optical and electrochemical studies like electrocatalysis, solar cells, biosensing, etc. Due to their stability and toxicity, the enhancement of CPNs' properties was the primary cause of concern. Herein, we synthesized Nitrogen-doped (N-doped) N-CPNs using the one-step hydrothermal approach of PVA and PVDF polymers with Nitric acid (HNO₃) as the nitrogen source. The luminescence intensity was observed to be enhanced by increasing nitrogen doping concentration. The synthesized fluorescent samples exhibited significant antibacterial properties, making them useful in biomarkers, sensing strategies, drug delivery, etc. Doped PVA samples exhibited negligible antibacterial activity, but nitrogen-doped PVDF samples displayed considerable biocidal activity against gram-positive bacteria, according to antibacterial research. Each sample's growth inhibition was distinct and species-specific.

氮掺杂碳化聚合物纳米材料(N-CPNs)的荧光增强及抗菌性能研究

近年来，碳化聚合物纳米材料在电催化、太阳能电池、生物传感等各种光学和电化学研究中得到了广泛的应用，引起了人们的广泛关注。由于其稳定性和毒性，cpn性能的增强是引起关注的主要原因。本文以硝酸(HNO3)为氮源，利用PVA和PVDF聚合物一步水热法合成了氮掺杂(n掺杂)N-CPNs。随着氮掺杂浓度的增加，发光强度增强。合成的荧光样品具有显著的抗菌性能，可用于生物标志物、传感策略、药物传递等方面。根据抗菌研究，掺杂PVA样品的抗菌活性可以忽略不计，但氮掺杂PVDF样品对革兰氏阳性细菌表现出相当大的杀灭活性。每个样品的生长抑制是不同的，并且是物种特异性的。
